ObjectiveTo investigate the therapeutic effect of Astragali Radix-mediated changes in gut microbiota on treating type 2 diabetes (T2DM). MethodsA 12-week randomized, placebo-controlled clinical trial enrolled eighty patients with newly diagnosed type 2 diabetes and poor glycemic control in the Qi deficiency type. All patients received insulin therapy. The observation group (40 cases) was administered with Astragali Radix Granules, while the control group (40 cases) received a placebo. Both treamtents were taken orally twice daily. Changes in gut microbiota were assessed by 16s rDNA sequencing. Serum glucagon-like peptide-1 (GLP-1) levels were measured using enzyme-linked immunosorbent assay (ELISA). Glucose metabolism indicators including fasting blood glucose (FPG), 2-hour postprandial blood glucose (2 h PG),glycated albumin(GA), and glycated hemoglobin (HbA1c) were evaluated. Pancreatic function was evaluated using fasting C-peptide (FCP), 2-hour postprandial C-peptide (2 h CP), and C-peptide area under the curve (AUCcp). Traditional Chinese medicine (TCM) syndrome scores, clinical efficacy, and safety indicators were also observed. ResultsIn terms of glucose metabolism indicators, compared with the baseline, both groups exhibited significantly lower FPG, 2 h PG, GA and HbA1C (P<0.01),while FCP, 2 h CP and AUCcp were significantly higher (P<0.01). Compared with the control group after the treatment, the observation group showed significantly lower FPG, 2 h PG, GA and HbA1C(P<0.05, P<0.01),and significantly higher FCP, 2 h CP and AUCcp (P<0.05, P<0.01), indicating that Astragali Radix can improve glucose metabolism. In terms of the diversity of gut microbiota, no significant differences were detected in the Chao1, Shannon and Simpson indexes of the two groups compared with their respective baselines. However, compared with the post-treatment control group, the observation group demonstrated significant increases in the Chao1, Shannon and Simpson indexes (P<0.05, P<0.01). The β-diversity analysis showed significant separation in gut microbiota composition before and after treatment in both groups, indicating that Astragali Radix can significantly alter the structure and improve the diversity of gut microbiota. At the phylum level, compared with the baseline, both groups showed a significant increase in the relative abundance of Bacteroidota(P<0.01). The relative abundance of the potentially harmful phylum Proteobacteria was significantly lower in the observation Group after treatment (P<0.01). Compared with the post-treatment control group, the observation group had a significantly higher relative abundance of Bacteroidota(P<0.01). No significant difference was found in Firmicutes/Bacteroidota (F/B) ratio between the two groups after treatment, and other phyla showed no significant differences. At the genus level, compared with the baseline, the observation group exhibited a significant increase in Bacteroides (P<0.01) and a significant decrease in Escherichia-Shigella (P<0.01), whereas no significant difference was seen in the control group . Compared with the control group after treatment, the observation group after treatment had a significantly higher relative abundance of Bacteroides (P<0.01). No significant differences were seen in other genera. Linear discriminant analysis (LDA) identified potential characteristics taxa: in the observation group, Bacteroidota at the phylum level and Bacteroides and Dubosiella at the genus level, in the control group, Proteobacteria at the phylum level as well as Barnesiella and Staphylococcus at the genus level. Correlation analysis based on a heatmap revealed that GLP-1 levels were positively correlated with Firmicutes, F/B ratio and Fusobacterium, and negatively correlated with Bacteroidota, Proteobacteria, Bacteroides and Escherichia-Shigella. In terms of clinical efficacy, compared with the control group, the total effective rate of the observation group was significantly higher (P<0.05). Compared with the baseline, the scores for shortness of breath, fatigue, weakness, spontaneous sweating and reluctance to speak significantly decreased in both groups (P<0.01). Compared with the control group after treatment, the score for weakness was significantly lower in the observation group (P<0.01),indicating that Astragali Radix could improve clinical symptoms and alleviate weakness symptoms. In terms of safety, compared with the baseline, alanine aminotransferase (ALT) levels significantly decreased in both groups (P<0.05,P<0.01),indicating that Astragali Radix did not induce any significant abnormalities in liver and kidney functions. ConclusionAstragali Radix demonstrates the potential to significantly improve the gut microbiota environment in patients of newly diagnosed type 2 diabetes with Qi deficiency. The therapeutic effect may contribute to glycemic control, possibly mediated by an elevation in GLP-1 level. These findings may support its further clinical investigations and potential applications.

ObjectiveTo elucidate the efficacy connotation of Shudi Qiangjin pills (SQP) against liver and kidney deficiency in steroid-induced osteonecrosis of femoral head (SONFH) from the perspective of the "disease-syndrome-formula" association and to clarify the underlying mechanisms based on in vivo and in vitro experiment validation. MethodsThe chemical components and the corresponding putative targets of SQP were collected from the Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0, the Encyclopedia of Traditional Chinese Medicine (ETCM) v2.0, and HERB databases. The SONFH-related genes were identified based on the differential expression profiles of peripheral blood of patients with SONFH compared to the healthy volunteers, and the disease phenotype-related targets were collected from the TCMIP v2.0 database. Then, the interaction network of "SONFH-related genes and candidate targets of SQP" was constructed based on "gene-gene interaction information", and the major network targets were screened by calculating the topological characteristic values of the network followed by the functional mining according to the Kyoto Encyclopedia of Genes and Genomes (KEGG) database and the SoFDA database. After that, the SONFH rat model was prepared by lipopolysaccharide combined with methylprednisolone injection, and 2.5, 5, 7.5 g·kg-1 SQP (once per day, equivalent to 1, 2, and 3 times the clinical equivalent dose, respectively) or 7.3×10-3 g·kg-1 of alendronate sodium (ALS, once per week, equivalent to the clinical equivalent dose) was given for 8 weeks. The effect characteristics of SQP and ALS in the treatment of SONFH were evaluated by micro-computed tomography scanning, hematoxylin and eosin staining, alkaline phosphatase (ALP) staining, immunohistochemical staining, enzyme-linked immunosorbent assay, and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL)staining, and a comparative efficacy analysis was conducted with ALS. In addition, SONFH cell models were prepared by dexamethasone stimulation of osteoblasts, and the intervention was carried out with the medicated serum of SQP at the aforementioned three doses. Cell counting kit-8, ALP staining, ALP activity assay, alizarin red staining, and flow cytometry were employed to investigate the regulatory effect of SQP on osteoblasts. The expression levels of osteogenesis-related proteins and key factors of the target signaling axis were detected by quantitative real-time polymerase chain reaction and Western blot. ResultsThe network analysis results demonstrated that the candidate targets of SQP primarily exerted their therapeutic effects through key signaling pathways, including phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt), lipid metabolism and atherosclerosis, prolactin, chemokines, and neurotrophic factors pathways. These pathways were significantly involved in critical biological processes such as muscle and bone metabolism and the regulation of the "neuro-endocrine-immune" network, thereby addressing both modern medical symptoms (e.g., delayed skeletal maturation and recurrent fractures) and traditional Chinese medicine (TCM) symptoms (e.g., fatigue, aversion to cold, cold limbs, and pain in the limbs and joints in patients with SONFH characterized by liver and kidney deficiency syndrome. Among these pathways, the PI3K/Akt signaling pathway exhibited the highest degree of enrichment. The in vivo experimental results demonstrated that starting from the 4th week after modeling, the modeling group exhibited a significant reduction in body weight compared to the control group (P<0.05). After six weeks of treatment, all dosage groups of SQP showed significantly higher body weights compared to the model group (P<0.01). Compared with the normal group, the model group exhibited significant decreases in bone mineral density (BMD), bone volume fraction (BV/TV), trabecular number (Tb.N), osteocalcin (OCN), alkaline phosphatase (ALP) levels in femoral head tissue, and serum bone-specific alkaline phosphatase (BALP) (P<0.01), along with significant increases in trabecular separation (Tb.Sp), empty lacunae rate in tissue, and apoptosis rate (P<0.01). In comparison to the model group, the SQP intervention groups showed significant improvements in BMD, BV/TV and Tb.N (P<0.01), significant reductions in Tb.Sp, empty lacunae rate and apoptosis rate (P<0.05), and significant increases in protein levels of OCN and ALP as well as BALP content (P<0.05). The in vitro experimental results revealed that all dosage groups of SQP medicated serum showed no toxic effects on osteoblast. Compared with the normal group, the model group displayed significant suppression of osteoblast proliferation activity, ALP activity, and calcified nodule formation rate (P<0.01), significant decreases in mRNA transcription levels of OCN and Runt-related transcription factor 2 (RUNX2) (P<0.01), significant reductions in protein content of osteopontin (OPN), typeⅠ collagen (ColⅠ)A1, B-cell lymphoma-2 (Bcl-2), PI3K, and phosphorylated (p)-Akt (P<0.01), and a significant increase in apoptosis rate (P<0.01). Compared with the model group, the SQP medicated serum intervention groups exhibited significant increases in proliferation activity, ALP activity, calcified nodule formation rate, mRNA transcription levels of OCN and RUNX2, and protein content of OPN, ColⅠA1, Bcl-2, PI3K, and p-Akt (P<0.05), along with a significant decrease in apoptosis rate (P<0.01). ConclusionSQP can effectively reduce the disease severity of SONFH with liver and kidney deficiency syndrome and improve bone microstructure, with the therapeutic effects exhibiting a dose-dependent manner. The mechanism may be related to its regulation of key processes such as muscle and bone metabolism and the correction of imbalances in the "neuro-endocrine-immune" network, thereby promoting osteoblast differentiation and inhibiting osteoblast apoptosis. The PI3K/Akt signaling axis is likely one of the key pathways through which this formula exerts its effects.

AIM: To compare the preoperative ocular biometry between Pentacam AXL and IOL Master 700 in cataract patients.METHODS:Prospective study. A total of 150 patients(150 eyes)with cataracts who were treated in our hospital from May to December 2024 were selected. The IOL Master 700 and Pentacam AXL were preoperatively used to measure axial length(AL), corneal curvature(K1, K2 and Km), anterior chamber depth(ACD), and white-to-white(WTW). The difference and consistency of the results of the two instruments were compared.RESULTS: There was no significant difference between the two instruments in the AL, K1, K2, Km, ACD, and WTW(all P>0.05). The Spearman correlation analysis showed that the two instruments positively correlated with the AL, K1, K2, Km, ACD and WTW of the operated eye(all P<0.001). The Bland-Altman analysis showed that for the Pentacam AXL and IOL Master 700, there were 5/150(3.3%), 7/150(4.7%), 4/150(2.7%), 5/150(3.3%), and 0 points outside the 95%LoA for the AL, K1, K2, Km, ACD, and WTW of the examined eyes, respectively, with all of these values less than 5%, indicating good consistency.CONCLUSION:The AL, K1, K2, Km, ACD and WTW of Pentacam AXL and IOL Master 700 in cataract patients before cataract phacoemulsification combined with IOL implantation show no significant differences, and have good correlation and consistency. The two instruments can be used interchangeably.

Ulcerative colitis (UC) is a common digestive disease characterized by recurrence and remission alternation,which seriously affects the life quality and physical and mental health of patients. The pathogenesis of UC is complex,and studies have shown that the occurrence and development of UC are closely related to the transduction of multiple signaling pathways. The current western medicine treatment has many problems,such as single action target,more adverse reactions,poor patient tolerance,and easy recurrence after stopping the medicine. Traditional Chinese medicine has the advantages such as multi-targets,multi-pathways, and fewer adverse reactions, elucidating that the action mechanism of traditional Chinese medicine in the treatment of UC is the focus of current research. Therefore, this paper conducted a systematic review on how traditional Chinese medicine exerts therapeutic effects by regulating the signaling pathways related to UC in recent years,and it was found that traditional Chinese medicine can regulate nuclear factor-κB (NF-κB),adenylate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR),Janus tyrosine protein kinase (JAK)/signal transducer and activator of transcription (STAT),phosphatidylinositol 3-kinase (PI3K) /protein kinase B (Akt),NOD-like receptor thermoprotein structural domain-related protein 3 (NLRP3)/cysteine protease-1 (Caspase-1),nuclear respiratory factor 2 (Nrf2)/heme oxygenase-1 (HO-1), and several other pathways,thereby inhibiting oxidative stress and cellular pyroptosis,regulating the Tregs/Th17 cellular balance, promoting autophagic response and M2-type macrophage polarization,restoring the diversity and abundance of intestinal flora,promoting the repair of intestinal mucosal barrier function,and alleviating the inflammatory damage of UC colonic tissues. The holistic concept and evidence-based treatment of traditional Chinese medicine were combined with the modern molecular mechanism research of traditional Chinese medicine, and the traditional Chinese medicine combinations with different mechanisms, following regulation, were formulated into compound formulas or pairs of medicines according to the pattern of evidence. It is expected to achieve better therapeutic efficacy and to provide ideas and references for the modification of classic compound formulae of traditional Chinese medicine in UC treatment and clinical translation.

ObjectiveTo explore the potential mechanism of Xiaoqinglong Decoction (小青龙汤, XD) in the treatment of allergic rhinitis. MethodsForty-five rats were randomly assigned to a control group, a model group, a loratadine group, low-, medium- and high-dose XD groups, and low-, medium- and high-dose Mahuang Decoction and Cang'erzi Powder (麻黄汤合苍耳子散, MDCP) groups. Except for the control group, rats were administered with ovalbumin (OVA) and aluminum hydroxide via intraperitoneal injection for 14 days to establish an allergic rhinitis model. After the 14th-day injection, nasal stimulation was continued with 20 μl of 10% OVA solution to maintain the model. Rats in the control group and the model group received 10 ml/(kg·d) of saline, whereas those in the loratadine group were administered with 0.9 mg/(kg·d) of loratadine. The low-, medium- and high-dose XD groups were administered XD at the dose of 2.7, 5.4, and 10.8 g/(kg·d), respectively. The low-, medium- and high-dose MDCP groups were administered MDCP at the dose of 2.43, 4.86, and 9.72 g/(kg·d), respectively. All treatments were administered by gavage once daily for 7 consecutive days. One hour after the final gavage, nasal symptom scores were recorded for all group of rats. The next day, serum levels of immunoglobulin E (IgE), interleukin-4 (IL-4), and interleukin-13 (IL-13) were measured. HE staining was used to observe the pathological morphology of the nasal mucosal tissue. Quantitative reverse transcription PCR (RT-qPCR) and Western Blot were performed to assess mRNA and protein expression of thymic stromal lymphopoietin (TSLP) and OX40 ligand (OX40L) in the nasal mucosa. ResultsCompared to the control group, total nasal symptom score in the model group significantly increased (P<0.01). HE staining revealed disrupted and adhered cilia, thickened basement membranes, and extensive inflammatory cell infiltration in the nasal mucosa. Serum levels of total IgE, IL-4, and IL-13, as well as TSLP and OX40L mRNA and protein expression in the nasal mucosa, were significantly elevated in the model group (P<0.05 or P<0.01). Compared to the model group, the total nasal symptom scores in all drug intervention groups were significantly reduced; the serum total IgE levels in the loratadine group, the low- and medium-dose XD groups, and the low- and high-dose MDCP groups were significantly reduced; and the serum levels of IL-4 and IL-13 in the high-dose XD group and the high-dose MDCP group decreased (P<0.05 or P<0.01). Nasal mucosal structure was improved. Except for the low-dose MDCP group, all other intervention groups showed a significant reduction in TSLP and OX40L mRNA expression in the nasal mucosa (P<0.01). All doses of XD and the medium- and high-dose MDCP groups significantly decreased the protein levels of TSLP and OX40L (P<0.05). The medium-dose XD group exhibited more improvement of nasal symptom scores and greater suppression of expression of TSLP and OX40L mRNA, and TSLP protein levels compared to the loratadine group (P<0.05). ConclusionXD may protect nasal mucosa of rats and alleviate allergic rhinitis by suppressing the TSLP/OX40L pathway, thereby attenuating Th2-mediated immune responses.

Objective To explore the number of peripheral blood regulatory T cells (Treg) in patients with chronic kidney disease (CKD) and its correlation with vascular calcification. Methods This was a single-center, cross-sectional, and observational study. Non-dialysis patients with CKD treated at Zhongshan Hospital, Fudan University from March 2021 to March 2022 were enrolled. Abdominal aortic calcification (AAC) was assessed using lateral abdominal X-ray. Number of Treg and cytokine levels were measured by flow cytometry. Logistic regression analysis was performed to evaluate the related factors for AAC in CKD patients. Results A total of 83 patients were included, aged 17–86 years, with 57 males (68.7%). The distribution of CKD stages was as follows: stage G1 in 7 patients (8.4%), stage G2 in 17 patients (20.5%), stage G3 in 21 patients (25.3%), stage G4 in 19 patients (22.9%), and stage G5 in 19 patients (22.9%). No AAC was observed in patients with stages G1 and G2, while the prevalence of AAC in patients with stages G3, G4, and G5 was 23.8%, 21.1%, and 26.3%, respectively. Compared with stage G1 patients, those with stages G3–5 showed decreased number of peripheral blood Treg and elevated levels of interleukin (IL)-6 and IL-17F (P<0.05). The area under the receiver operating characteristic curve for number of peripheral blood Treg in predicting AAC in CKD patients was 0.766 (95%CI 0.652–0.879, P=0.002). Logistic regression analysis showed that decreased number of Treg was related factor for AAC in CKD patients (OR=0.957, 95%CI 0.922–0.992, P=0.018). Conclusion As CKD progresses, number of peripheral blood Treg significantly decreases, which is correlated with AAC in CKD patients.

Sichuan Province is a hilly schistosomiasis-endemic province in China with the highest endemicity and largest coverage. During the period of more than 70 years of integrated control, there are five distinct phases of schistosomiasis control in Sichuan Province, including baseline investigation, Oncomelania hupensis snail control, chemotherapy for both humans and livestock, management of source of Schistosoma japonicum infections, and sustained control and intensified surveillance and early warning, and a package of key interventions are implemented, including environmental modification, snail control with chemical treatment, large-scale chemotherapy for humans and livestock, management of source of S. japonicum infections, intensified integrated control, establishment of an early warning and surveillance system. As a result, schistosomiasis has been eliminated across all 63 disease-endemic counties (cities, districts) in Sichuan Province by June 2025. Government-led multi-sectoral collaborations, science and technology-supported precision control strategies, and a sustainable control model tailored to the ecological and socio-economic conditions in endemic regions are essential to achieving the target of schistosomiasis elimination in Sichuan Province.

This paper systematically analyzes schistosomiasis transmission risks during the elimination stage and reviews the evolution of the schistosomiasis surveillance system in China from a One Health perspective, with a special emphasis on schistosomiasis surveillance and response practices during the elimination stage from a One Health perspective. These practices include precise screening of human schistosomiasis under low-endemicity conditions, systematic monitoring of schistosomiasis in domestic and wild animals, ecological management of Oncomelania snails, and information-coordinated responses. Nevertheless, the current surveillance and response system for schistosomiasis suffers from challenges of insufficient cross-sectoral coordination and complex external environments, which constrain precise schistosomiasis surveillance and response in China. Therefore, it is urgently necessary to integrate coordination mechanisms, empower the surveillance system with technological innovation, improve capacity building, and actively promote diverse social participation in the One Health framework, so as to consolidate current schistosomiasis control achievements and achieve the target for schistosomiasis elimination across China, which may provide a replicable technical model for global zoonoses control.
